IMPROVED COMPOSITION FOR SIZING AND STIFFENING FLOOR-CLOTHS, dc.

Specification forming part of Lettcrs Patent No. 36,794, dated Ociober28. 1862.

To all whom it may concern:

Be it known that I, N. B. POWERS, of Lam singburg, in the county ofRensselaer and State seed or any other drying-oils, to be applied tocanvas used in the manufacture of floor oilcloths, or to other textilefabrics or paper.

My composition is made by mixing a quantity of lime, with or withoutdrying-oils,with blood as it comes from the veins of cattle or otheranimals, in about the following proportions: Blood, two parts; lime, onepart, by weight; or the composition may also be made by dissolving thelime in water and mixing the lime-water with the blood. The proportionswhich I have named above must be varied for different kinds of blood,and according to the quality of lime. After the lime has been perfectlymixed with the blood, orin case lime-water is used after said solutionhas been intimately mixedwith the blood, the compo sition is ready to beused; and it must be remarked that it ought to be used up within a fewhours, as it sets or hardens so much as to be unfit for the purposeintended. The oil may be added after the lime has been intimately mixedwith the blood. By applying this sizing compound to canvas the latter isrendered fit to be used in the manufacture of floor oil-cloths; but itmust be remarked that my compound is equally applicable for sizing othertextile fabrics or paper.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The employment or use of a sizing com pound made of the ingredientsherein specified and mixed together in about the proportions set forth.

N. B. POWERS."
